Hello,

I am very inexperienced with R.

I am trying to download ChAMP package for methylation analysis.

The way I did this was by going to Bioconductor ChAMP url and opening R script.

I copied the scripts onto R studio. Most of the package downloaded.

I got one warning message

package ‘BiocInstaller’ was built under R version 3.2.0 

I had R 3.1.0 version. Initially I ignored this message and went to the next command

library(ChAMP)

which again I copied and pasted on my console. I got error message

Error in library(ChAMP) : there is no package called ‘ChAMP’

I thought this may be due to older R version. So I downloaded the latest version R3.3.1

and tried the library command again. I got the same error message.

Thanks in advance for the help

Looking at the R script, the call to biocLite loads the dependency packages.  Did you also run biocLite("ChAMP")  to install the ChAMP  package?  

You might also consider running biocLite()  to make sure your packages are up-to-date.
